Taye Diggs Dating Model Amanza Smith Brown

Just four months after it was announced that he and Broadway star Idina Menzel had split up after nearly 11 years of marriage, E! News has learned that the actor is now seeing model Amanza Smith Brown.

"They are 100 percent in love," a source tells E! News. "They have been dating for a while."

Our eyewitness says the pretty pair appeared completely enamored with each other that night, noting that Diggs "wasn't shy about her."

In December, reps for Diggs and Menzel told E! News in a statement, "Idina Menzel and Taye Diggs have jointly decided to separate at this time. Their primary focus and concern is for their son. We ask that you respect their privacy during this time."

Their son, Walker, is 4.

Diggs and Menzel, who met as members of the original Broadway cast of Rent in 1995, tied the knot on Jan. 11, 2003.
